I fear my FIP is dying: I have negative power going uphill (i.e., I slow down despite flooring it), and I've read elsewhere in these forums that these units are frequent "victims" of using WVO for fuel (which I do). There are other possibilities, I know (e.g., in another thread about my MAF code having been triggered, it's been suggested that I probably have one or more leaks in my air/vacuum system) but I'm planning for the worst.
My question is, I've been assuming that I'd have to replace the pump, but a mechanic around here with a stellar rep w.r.t. working on German cars, told me that, on account of something having to do with the computer being custom tuned to the pump (or some such) on each car, rebuilding is much less expensive and actually a better option. Fellow readers who know: do you concur?
Also, I fear there may be cavitation pitting on the internal metal parts of the pump: if there, mere rebuilding won't fix these, correct? If any pitting is not too bad, is the pump then still usable after rebuild, or does any pitting at all render the pump unusable?
Finally, where is the FIP, what does it look like, and how hard is it to remove?
Thanks!

PS: what is the "tandem pump," i.e., what does it do? Thanks again!
